To thermally crack large hydrocarbon chains, two key conditions are required: high temperature and low pressure. The elevated temperatures, typically ranging from 450 to 750 degrees Celsius, provide the energy needed to break the carbon-carbon bonds in the hydrocarbon chains. Low pressure helps facilitate the reaction and encourages the formation of smaller hydrocarbon products. This process is commonly used in petrochemical industries to produce fuels and other valuable chemicals.

Why paraffin oil have such a high boiling point?
Paraffin oil has a high boiling point because it consists of large hydrocarbon molecules with strong intermolecular forces. These forces require a significant amount of energy to overcome, resulting in a high boiling point. Additionally, the long carbon chains in paraffin oil allow for more potential interactions between molecules, further contributing to its high boiling point.
What is the lower explosive limit of hydrocarbon product?
The lower explosive limit (LEL) of a hydrocarbon product is the minimum concentration of vapor in the air that is needed to create an explosive mixture. It varies depending on the specific hydrocarbon product but typically falls between 1-5% of the air by volume. Operating within safe limits is crucial to prevent the risk of explosions.
What is needed for germination?
warmth and moisture is needed, so are the right air and light conditions
Why would more reactive metal take longer to thermally decompose?
A more reactive metal would take longer to thermally decompose because it has stronger metallic bonds that require more energy to break. These stronger bonds result in a higher activation energy needed for the decomposition process to occur. As a result, the reaction proceeds at a slower rate, leading to a longer decomposition time compared to less reactive metals with weaker metallic bonds.
What conditions are needed for catalytic cracking to happen?
Catalytic cracking requires specific conditions such as high temperature (typically between 450-550°C) and moderate pressure. The presence of a catalyst, usually a solid acid catalyst like zeolite, is essential to facilitate the breaking of larger hydrocarbon molecules into smaller, more valuable products like gasoline and diesel. Additionally, a controlled feedstock composition and proper residence time in the reactor are important for optimizing the cracking process.
How do you properly install and use snow chains on your boots for added traction in icy or snowy conditions?
To properly install and use snow chains on your boots for added traction in icy or snowy conditions, follow these steps: Lay the snow chains flat on the ground and step into them with your boots. Pull the chains up and secure them tightly around your boots. Adjust the chains to ensure a snug fit and proper traction. Walk carefully and slowly to test the traction of the snow chains on the icy or snowy surface. Remove the snow chains when not needed to prevent damage to them and your boots. Remember to always follow the manufacturer's instructions for the specific snow chains you are using.
How can I effectively use snow chains for shoes to improve traction in icy conditions?
To effectively use snow chains for shoes in icy conditions, first ensure they are the correct size and securely fastened. Place them over the sole of your shoe, making sure they are evenly distributed. Walk carefully and deliberately to maintain traction on icy surfaces. Remove the snow chains when not needed to prevent damage to shoes or floors.
What are two conditions needed to crack paraffin?
Two conditions needed to crack paraffin are high temperature (around 500-900 degrees Celsius) and the presence of a suitable catalyst. Cracking breaks down larger hydrocarbon molecules like paraffin into smaller, more valuable hydrocarbons like ethylene and propylene.
What is needed for nitrogen oxides to be produced when hydrocarbon fuels are burned?
very high temperatures
What size tire chains are needed for a 1999 Toyota tacoma?
The correct chains will match the tire size.
Why paraffin oil have such a high boiling point?

Additionally, the long carbon chains in paraffin oil allow for more potential interactions between molecules, further contributing to its high boiling point.
What is needed for Pharm tech certification?
Retail pharmacy is probably not the ideal environment for pharmacy technicians just starting out. The working conditions that are present in most retail chain pharmacy chains are very negative
Does a roller coaster have gears?
Yes. They are needed too operate the chains
Why is cracking useful?
cracking is useful because large hydrocarbon molecules are broken into smaller ones. And these are needed for petrol and are more reactive.
What class of organic compounds stores energy as fat?
Lipids are the class of organic compounds that store energy as fat in living organisms. They consist of molecules such as fats, oils, and waxes that are insoluble in water and contain long hydrocarbon chains. Stored fats can be broken down to provide energy when needed by cells.
